Help me with Brushless CRT.5

[DRIFT_BUGGY]

Alright, I have pretty much decided on what gear to run.
I am going to be running the Tekin 3700KV motor and Mamba Max ESC (with fan) while running ProTek 3S 20C 4000mAh. Will keep running the standard size tyres. What gearing should I start off with? The track is fairly large.

Also, what Gear Ratio do most people aim for with the BL CRT.5? Running 3700KV x 11.1 (41070RPM) and 14T Pinion and 46T Spur with Stuck Buggy Tyres (3.5") the drive ratio is 10.68:1
